Phys.org / Why social media algorithms send you posts you don't like
Do your social media accounts feed you content that reflects your core beliefs and guiding principles? Our new research published in the Proceedings of the National Academy of Sciences shows that the algorithms supplying ...
Tech Xplore / Engineers connect bacteria to create living transistors
MIT researchers have engineered bacteria that can function as transistors, allowing the team to create living "circuit boards" that can be printed onto a growth medium in a Petri dish.
Phys.org / Einstein Probe catches rare X-ray flash from an exploding star
Astronomers have linked an X-ray flash discovered by the Einstein Probe to a known type of supernova with unusual features that point to the birth of an ultra-dense, rapidly spinning magnetar. The paper outlining this finding ...
Medical Xpress / FDA authorizes first standalone robotic device to draw blood
The U.S. Food and Drug Administration has authorized Aletta as the first standalone robotic device that can draw blood from a patient's arm. Marketing authorization was granted to Vitestro.
Medical Xpress / T cells ditch exhaustion marker to escape tumors and protect against cancer relapse
As the immune system battles cancer, chronic stimulation gradually drives T cells to a state of exhaustion. But some of these exhausted T cells can lose expression of the exhaustion marker LAG3, move out of the tumor and ...
Phys.org / Illuminating the limits of the international unit of light, the candela
The candela, the international unit of light in use for almost a century, forms the basis of photometry. According to a new study, measurements derived from it systematically misjudge the brightness of colored light sources ...
Medical Xpress / Aging reprograms skin genetic activity and promotes inflammation, study reveals
As we age, the skin loses part of its ability to regenerate, heal wounds and maintain an effective barrier against the outside world. Among the causes of this deterioration is low-grade, persistent age-associated inflammation, ...
Phys.org / How sex sheds evolutionary baggage
Why is there sex—or, more precisely, sexual reproduction? If you're an evolutionary biologist, the answer isn't obvious. Sexual reproduction is biologically costly, requiring not only competition for mates but also the creation ...
Medical Xpress / Human multi-organ chip tracks breast cancer spread to bone and lung
Cancer spreading beyond the primary tumor—a process known as metastasis—is responsible for at least two-thirds of cancer deaths. Drugs targeting metastatic progression have largely failed, in part because of the lack of predictive ...
Medical Xpress / Living near dry cleaners linked to increased likelihood of Parkinson's disease
People living near dry cleaners may have a higher risk of developing Parkinson's disease, according to a new nationwide study led by researchers at Barrow Neurological Institute in Phoenix.
Phys.org / 3D-printed ceramic waveguide lasers could surpass the power of glass fiber lasers by 10 times
At the bottom of the ocean, optical fibers transmit telecommunications and internet data around the world. Waveguides make that feat possible by channeling and amplifying the light—and therefore the data within—over enormous ...
Medical Xpress / Submillimeter MRI reveals brain hubs that guide risky decisions
Imagine that a notification on your financial app captures your attention about a stock projected to have a 68% chance of doubling your investment within a month, with a 32% chance of total loss. Would you commit a $50,000 ...
